HANS EBERHARDT, OF BERLIN, GERMANY.

SPRING-BUTTON FOR GLOVES, ARTICLES OF CLOTHING, SHGES, AND THE LIKE.

To all 'whom it may concern:

Be it known that I, HANS EBERHARDT, resident of l Flensburgerstrasse, Berlin, Germany, manufacturer, have invented a new and useful Improvement in Spring-Buttons for Gloves, Articles of Clothing, Shoes, and the Lilie.

My invention consists in manufacturing spring-buttons Which are made undetachable by a lateral pull, no matter on which side, by a peculiar simple arrangement. In consequence of this new feature the button can be used also for such objects in Vwhich a great lateral pull takes place, for instance shoes and boots. rI`he applicability of the button is, in consequence of the present ar rangement, considerably enlarged.

The neuT feature consists in giving to one part of the button, which per se is already known, With its border' a point of support on the border of the other part in any pulling direction. The lateral pull exerted on the button finds therefore in the first place on this point of support a resistance and from this the pulling force is transmitted under a very acute angle to the juncture properly speaking of the button. In consequence of the transmission of force under an acute angle the said juncture is influenced by the pull only in a very small degree. Moreover With a lateral pull one part of the button must, as is Well known, be turned out of the other. By the arrangement of a supporting point on the border of one of the parts of the button it is made impossible, by the lengtln ening of the radius from the supporting point of the resilient or rigid part of the button toward the friction-surface of the latter', for the arts to become separated.

T e arrangement of the point of support in question can be made in different Ways. The most simple form is a projecting border on the upper or lower part of the button or a recess in the buttoneplate, so that the plate 0f the other part can be inserted into the same. The Obj ect of my invention is shown in this form of construction on an enlarged scale on the accompanying drawing, in Which- Figure 1 is a cross-section, Fig. 2 shows the Working parts of this button, Fig. 3 is a modified form of the button shown in Fig. 2.

The button according to Fig. l consists in Specification of Letters Patent.

the usual manner of an upper, female part a, into -which is forced the resilient or rigid part l). T1lilith the female part a is connected the hood c with the guide-rings d and e. Between the ring e and the flat border of the female part a is the stuff, on which this part of the button is xed, compressed by forming a border around the border of the neck of the part a. The other part of the button consists of the resilient or stiff crown f) and the plate g for compressing the stuff 7L. The netv feature consists therein that the flange i of the part l) of the crown is sunk into the flange k of the female part, so that the edge ofthe flange 'i finds a support on the flange This arrangement may, of course, also be the reverse, so that (Fig. 3) the border of the female part a is sunlr into the border of the part b of the crown.

The mode of working of the nev.'v construction can be seen from Fig. 2. If the pull takes place with both buttons in the direction of the arroufs l the arcs 2 indicate the r-:ays `which the crowns move `with regard to the female parts. It 'will be seen that the path of the crown of the neu' button according to Fig. 2 passes through the female part, whereas with the old button hitherto used the crown requires only a small pressure in order to pass along the inner -wall of the female part. The greater resistance of the .new button against a lateral pull is therefore quite evident.

Having now described my invention what I claim is:

l. In spring buttons, the combination of a cro'en part,` a female part, both of `which are provided '-.fith flanges, and means on the flange of one part for supporting the border of the flange of the other part, as and for the purpose specified.

2. In spring buttons, the combination of a crown part, a female part, both of 'which are provided 'with iianges and the fiange on one part being provided 'with a recess for supporting the border of the flange of the other part.

In Witness whereof I have hereunto set my hand in presence of two witnesses.

HANS EBERIIARDT.
